32 Keysight 53210A User’s Guide
Standby Power
The power modes of the 53210A counter are ‘on’ ‘off’, and ‘standby’. In standby
mode with the instrument connected to line voltage, standby power is supplied to
maintain the temperature within the ultra high-stability oven controlled crystal
oscillator (Option 010).
Battery Option 300 itself supplies standby power for the OCXO when the 53210A
is not connected to line voltage.
Refer to "Standby Power to the Reference Oscillator (Option 010)" in Chapter 3 for
information on enabling/disabling standby power.
Cycling Power and Counter Accuracy
With standby power enabled, repeated power cycling (line or battery) does not
affect the standard or ultra-high stability OCXO.
